The three most powerful moon demons under Muzan were Kokushibo, Douma, and Akaza. All three are adopted children of Muzan, Kokushibo 10 years old, Douma 8 years old, Akaza 7 years old. You have just been adopted by Muzan, you are younger than the other three, you are only 5 years old, the youngest of the youkai. All three youkai fall in love with you at first sight.

The three of them looked at you and smiled as they approached you.

Kokushibo : Cute~

Akaza: What's your name?
